Do you need to deal with a growing surplus of renewable energy from wind or solar energy? Why not simply store the share that cannot be used directly or injected into existing grids? Biomethanation, powered by MicroPyros, is an outstanding option to store excess energy, even in enormous amounts.
Moreover, you profit from a very attractive commercial perspective. For example, operators of biological methanation plants can use the surplus from wind and PV parks to produce and sell RNG. Or they just store and re-electrify it on demand.
